EXPANDlNG VEHICLE-HUB.

SPECIFICATION forming part of Letters Patent No. 781,076, dated January 31, 1905.

Application filed August l2, 1904. Serial No. 220,562.

To all whom it may concern.' v

Be it known that I, J AMns LARENCE OBR KING, a citizen of the United States, residing at Tokeena, in the county of Oconee and State Y of South Carolina, 'have invented certainV new and useful'Improvements in Expanding Vehicle-Hubs; and I do declare the following to be a full, clear, and exact description of the invention,` such as will enable others skilled in the art to which it appertains to make and use the same,reference being had to the accompany-1 ing drawings, and to the letters of reference marked thereon, which form a part of this specification.

` This invention relates to new and useful improvements in expanding hubs for vehiclewheels; and theobject of the invention is to produce a simple and eflicient device whereby the spokes of a 4,vehicle-wheel may-be easily and quickly tightened without the necessity of sending thewheel to a wheelwright or machinist. K Y The invention consists in various details of construction and in combinations and arrangements of parts, which will be hereinafter fully described and then specifically defined in the appended claim.

My invention is illustrated `in the accomlpanying drawings, which,'with the letters of reference marked thereon, form a part of this application, and in which drawings similar letters of reference indicate like parts in the views, in which- Figure 1 is avertic'al sectional view through a hub of a wheel embodying my improvements.y Fig.v 2 is a Vcross-sectional view -on line 2 2 of Fig. 1. -Fig. 3 is a sectional view of a modified form, and Fig. i is a side elevation of the modified form shown in Fig. 3.-

Reference nowi being had to the details of the drawings by letter, A `designates an axle of a wheel having a threaded end A' and an the circumference of the expanding-ring D,

against which spokes E bear. A washer F,

having elongated slots F therein, is positioned against the face of said flange and is positioned about'the circumference of the expanding-ring D.

The outer sectional hub of the wheel (designated by letter H) has a flanged portion H', and theface of said flanged portion is recessed, as at 7L, and is adapted to receive the enlarged end of a conical expanding member K. A washer J, having radial slots therein, is intertion H and the outer edges of the spokes and is similar to the washer F. Bolts O are passed through the registering radial slots in the two washers and' are positioned intermediate the spokes, and 4the said slots are elongated for the purpose of allowing the bolts to move slidingly with the spokes as they are expanded.

Referring to Fig. 3 of the drawings, it is seen that' I have slightly modified the form of" the expanding member, (designated in the drawings by letter K,)v in which the shanked portion of said member is of cylindrical shape, provided with circumferential threads,

K and adapted for engagement with the interior threads of the hub-section H, and the outer end ofsaid shanked portion is adapted to be engaged by a wrench for the purpose of rotating the same for tightening a spoke. In this form the axlesnut A2 lits against the end of the axle-box, and the interior portion of the vshanked portion of4 the expanding mem-ber K 'is chambered for vthe reception of said nut, as shown. By this means it will be observed that the spokes may be tightened without `the necessity of first removing the outer section of the hub, which in some instances is considered a desideratum.

By the provision of the apparatus described a simple and efficient means is provided for conveniently tightening spokes by the simple manipulation of the parts herein described.

I am aware that it is common in the art to construct expanding hubs of various kinds,v

and hence I make no particular claim for such construction.

While I have shown a particular detailed construction of apparatus illustrating the features of my invention, it will be understood that I may make alterations, if desired, in

6o posed between the fianged end of the hub-seci the detailed construction of the same without in any Way departing from the spirit of my invention.

Having thus fully described my invention, what l elaim as new, and desire to secure by Letters Patent, is-

An expandinghub Comprising, in combination with an axle and box therefor, a hub-seetion having a shoulder iitting over a shoulder upon said box, a conical-shaped member having a central threaded aperture adapted to lit threads upon said box, and a eliarnbered portion beyond the threaded portion oi' said aperture, a' spoke-expanding ring engaged by said conical-shaped member, Washers surrounding said expanding-ring and having ra- JAMES lnlliEXCll Ulill KING.
